Weather stripping exterior storm windows?

[SouthBend]

Recently I fixed a little bit of rot on four windows, and took the opportunity to reglaze the exterior wood storms which hang from the top and tilt out at the bottom during the summer. Got me thinking about weather stripping them because on at least one of them there's a substantial draft that can get by.

I contacted Jake at Wood Window Makeover, his response was "We use WS33 silicone cornerseal (1/4" diameter) around our storm windows. I've attached some photos to give you an idea." http://www.conservationtechnology.com/b ... nents.html

When I asked about the reasoning for weather stripping the storm itself, versus the inside corner where it meets, he said, "That is correct. Performance wise the seal will act the same in either place, but we've found that working on a storm window on the ground is much easier than on the actual window up a ladder. It also makes long-term maintenance easier for both windows."

Below are the photos he provided of how they do it, along with photos of my windows (before I painted sills). I was just wondering though if anyone had an opinion on the matter that might be helpful, or had done weatherstripping on their storms themselves. I'm inclined at least on the 1st floor to get the jig for a rotozip or whatnot to create the groove in the corner and put the weather stripping there but there is not a whole lot of information on the internet or videos that I can find. This is the power tool (corner grooving device) that conservation technology sells but I think there are more universal adapters for rotozips, routers, etc? http://www.conservationtechnology.com/b ... roove.html. Then add some of the metal snap fasteners like most of the other windows have to keep it sucked in. https://www.houseofantiquehardware.com/ ... ategory=91

I was trying to remember if this has come up for exterior storms, but can't remember. There is a thread here on this forum about using spring bronze weatherstipping for the windows themselves: Bronze Window Weather stripping. Jade's response (she's a professional wood window gal that is a member here) within that thread can be found here, which does mention a type of bulb WS as seems to have been recommended by the company you spoke with. She also has some links in her post that might help you.

There may be other threads that are storm WS specific, but the above is what came up first when I searched.
